Electric Toothbrush

The electric toothbrush is a kind of toothbrush invented by Philippe-Guy Woog. Through the rapid rotation or vibration of the motor core, the brush head generates high-frequency vibration, which instantly decomposes the toothpaste into fine foam and cleans the teeth deeply. At the same time, the bristles vibrate. It can promote blood circulation in the oral cavity and has a massage effect on the gum tissue.

In 1954, Swiss doctor Philippe-Guy Woog invented the electric toothbrush. Sixty years later, the electric toothbrush is very similar to this predecessor's.

In principle, there are two categories of electric toothbrushes: rotation and vibration. Rotary toothbrushes have a simple principle, that is, the motor drives the round brush head to rotate, which enhances the friction effect while performing ordinary brushing actions. The rotating toothbrushes are strong, clean the tooth surface, and clean the teeth relatively weakly. Long-term use is not recommended due to large wear and tear.

The vibration type toothbrush is more complicated and more expensive in terms of price. There is an electric-driven vibration motor inside the vibration type toothbrush, which can make the brush head produce high-frequency swings perpendicular to the direction of the brush handle, but the swing amplitude is very small, generally about 5 mm up and down, and the largest swing in the industry is 6. Mm.

When brushing teeth, on the one hand, the high-frequency swinging brush head can efficiently complete the action of scrubbing the teeth. On the other hand, the vibration of more than 30,000 times per minute also makes the mixture of toothpaste and water in the mouth produce a large number of tiny bubbles, which are generated when the bubbles burst. Pressure can penetrate deep between teeth to clean dirt.

There are three ways of movement of the brush head of an electric toothbrush: one is the brush head for reciprocating linear motion, the other is for rotating motion, and there is a complete set of electric toothbrushes with two brush heads. The bristles of the toothbrush head are made of soft plastic fibers, and the bristles are processed into a spherical shape, which will not damage the teeth and gums, nor affect the brushing effect. It can not only clean every tooth, but also massage the gums. There is a switch between strong and weak switching modes on the toothbrush handle, and the movement speed of the toothbrush head can be selected according to personal needs.

According to foreign reports, in the past few years, quite a few dentists have begun to recommend electric toothbrushes to their patients. An electric toothbrush is a tool for cleaning teeth. It consists of a rechargeable dry battery, a micro DC motor, a battery box, a toothbrush head, a metal shield and a sleeve; the dry battery used as the power source of the DC motor is installed in the battery box together with the DC motor. The battery box There is a manual switch for controlling the on and off of the DC motor power; the DC motor shaft extends out of the battery box, the toothbrush head and the metal shield are sleeved on the DC motor shaft, and there is a sleeve outside the toothbrush head and the metal shield. Electric toothbrushes equipped with different types of toothbrush heads can be suitable for various users.

In addition to daily use for brushing teeth, it can also be used to massage gums. When brushing teeth, it can be used for electric and manual purposes, and it can be used for brushing in vertical and horizontal directions. Through rhythmic tapping and rubbing of the gums, blood circulation can be enhanced. When used with drugs, the gums have a better absorption effect on drugs. It has a good therapeutic and preventive effect on common dental diseases such as periodontitis, gingivitis and gum bleeding. Using this brush can change the habit of horizontal brushing to vertical brushing. When brushing your teeth manually, the method is the same as that of a normal toothbrush.
